The substantial increase in power requirements for data centre operations over the last decade is resulting in a significant transformation in how the operators of these facilities secure resources.

Historically, data centres relied on local power distribution authorities for their electricity needs. However, the increasing demand has driven many operators to bypass these authorities, opting instead to engage directly with transmission networks.

Power Strategy

Data centres are now becoming some of the most energy-intensive facilities, necessitating a continuous and reliable power supply to maintain operations. As the digital economy accelerates, the demand for data storage and processing grows exponentially. This surge has compelled data centre operators to explore more efficient methods to secure power for their extensive infrastructures.

Traditionally, data centres relied on local power and water distribution companies to provide the necessary power to operate their facilities. These distribution companies, in turn, procured high-voltage power from higher-level transmission networks.

The rapid growth in energy demands is seeing several hyper-scale data centres, that require hundreds of megawatts of power, bypassing this traditional procurement model and seeking direct access to the transmission grid, which allows them to unlock three critical benefits: 1. negotiating lower costs by eliminating intermediaries, 2. saving time when securing power, and 3. increasing power demand predictability, with potential access to grid-scale renewable energy projects to support Power Purchase Agreements (PPAs) for green energy.

Several data centre projects involving direct connections with transmission networks, such as those worked on by Infravue, reported significantly improved power delivery times, reliability and efficiency. This has enhanced their operational capabilities and set a precedent for other operators to follow.

Despite the clear advantages, this shift is not without challenges. Engaging directly with transmission networks requires substantial investment, planning, and coordination, as regulatory frameworks were initially designed for smaller-scale, locally-connected facilities. Additionally, navigating regulatory and logistical hurdles is essential for ensuring seamless integration with existing infrastructure.

Water Strategy

While electricity receives most of the attention, water is another critical resource for data centres, especially those employing evaporative cooling systems. As operators secure locations and utilities for future builds, they also seek water rights or independent water sources, often through arrangements that bypass municipal water authorities. This can be challenging in water-stressed regions, potentially leading to community conflicts over resource prioritisation and increased pressure from regulators regarding large water usage volumes.

One solution is to implement closed-loop water systems, which require an initial upfront water requirement but subsequent minimal top-ups, as the system minimises water loss through evaporation or leakage. Whilst closed loop systems are slightly more energy intensive, they address the more significant issue of potable water availability and storage, resulting from these larger hyperscale facilities.

Conclusion

The evolution of power and water strategies in data centres marks a pivotal moment in the industry’s development. By bypassing local power authorities and engaging directly with transmission networks, data centre operators are redefining the path toward a more reliable and efficient future. The pressing question now is not whether this shift will continue, but how governments, communities, and existing utilities will adapt to this bold new paradigm.
